NAI L4 EXTRACTO R.

SPECIFICATION forming part of Letters Patent No. 502,914, dated Augusts, 1893.

l Y Application filed April 20,1593.. Serial No. 471,198- (No model.)

To all whom itk may concern:

Be it known that I, GEORGE H. SoRAN'roN, .I r., a citizen of the UnitedStates, residing at New Haven,in the county of New Haven and State ofConnecticut, have invented certain newan d useful Improvements inNail-Extractors; and I do hereby declare the followingto be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to the class of nail eX- tractors in which theoperative parts consist of a fixed jaw at the lower end of the shank, amovable jaw pivoted thereto and provided with a bearing lever by whichthe movable jaw is caused to grip the nail head between itself and thefixed jaw, and a sliding handle or rammer provided with a socketftoreceive the upper end of the shank; and my invention has for its objectto so improve the construction that heading or upsetting of the upperend of the shank in making the article shall be wholly unnecessary, andheading or upsetting to any appreciable extent in use shall be whollyavoided thereby rendering it impossible for the upper end of theshank-to stick in the socket, while at the same time the cost ofconstruction is reduced to the minimum.

With these ends in View I have devised-thenovel construction which Iwill now describe referring by numbers to the accompanying drawingsforming part of this specification in which- Figure 1 is a longitudinalsection of theY socket, the shank land jaws beingin elevation; Fig. 2 anedge view of the lower end of the shank and the jaws; Fig. 3 a sectionon the line a: in Fig. l looking down; Fig. 4 a section on the line y yin Fig. l looking up, and Fig. 5 is a section of the shank on the linexxbefore the lugs are turned as in Fig. 3.

It is of course well understood by those familiar with metal workingthat the simplest, cheapest and best way of raising projections of metalis to strike them out by means of a drop hammer, all drilling of metaland attachment of additional parts being thereby avoid- 5o ed. In themanufacture of this class of nail extractors the attachmentof the handleto the shank is quite an important step in the process of manufacture.This has been accomplished in various Ways as for vexample by drillingthe shank and driving a pin through, and also by heading or upsettingthe upper end of the shank. Asa matter of fact in use theconstant blowsof the ram mer upon the upper end of the shank tend to upset or head theupper end thereof to a greater or less extent. 6o For this reason it isdesirable not to head or upset the upper end of the shank in the man-4ufacture as the original heading or ange quickly becomes enlarged sothat there is danger of the shank sticking in the socket. I thereforeleave the upper end of the shank plain and provide means for retainingthe shank in the socket below the end of the shank which can be producedat a single operation and without drilling or the use of additionalpieces.

In the drawings 1 denotes the handle or rammer which is provided with asocket 2, the diameter' of the lower end of nsaid socket being reducedleaving a shoulder 3 and the re- 75 duced portion being provided withslots 4 through it. Near the upper end of the socket is cast atransverse hole 5. 6 denotes the shank, at the lower end of which is afixed jaw 7 to which a movable jaw 8 is pivoted, said movable jaw beingprovided with a bearing lever 9. These parts may all be of any ordinaryor preferred construction and are not of the essence of my invention.

`'In order to provide simple and inexpen- Vsive means for retaining theend of the shank in the socket without drilling and without upsetting orheading the upper end of the shank,

I place the upper end of the shank in a suitable die, and by means ofadrop hammer 9o strike out lugs or projections l0 the lower sides ofwhich are preferably formed at right angles to the shank so that theywill engage shoulder- 3 rmly. These lugs are made narrow enough so thatin assembling they will pass through slotsV 4 the lugs being at thismoment in the shape shown in Fig. 5. The assembler, then having passedthe shank into the upper end of the socket, inserts a tool from oppositesides into the hole 5 and gives roo the lugs a twist sidewise as clearlyshown in Fig. 3. This renders it impossible for the lugs to pass throughslots 4 again and prevents the shank from slipping out of the socket.

Having thus described my invention, I claim* In a nail extractor ahandle or rammel' havi ing the usual socket provided with a transversehole 5, and having at its lower end an internal shoulder with slots 4through it, in

combination with fixed and movable jaws the latter havinga bearinglever, and ashank by which the jaws are carried, the upper end ofpresence of two witnesses.
